Application filed Marcli 6, 1925. Serial No. 13,580.

My invention relates to certain improvements in electric switches of the type known, as through switches, which are used, principally, to regulate the amount of current passing to heat-ing'pads.

The object of the invention is to shape the two switch levers that project from the casing so that they are readily distinguishable. It will be understood that three de- M grees of heat can be used in this type of switch, the electric current being controlled by the switch levers.

In the accompanying "drawings: Fig. 1 is a perspective view of one form of through switch, illustrating my invention; Fig. 2 is a side view; and Fig. 3 is a plan view of the switch.

The casing 1 of the switch encloses the switch mechanism and is slotted at 2 and 3 for the switch levers 4 and 5, which are attached to independent switch mechanisms within the casing, and are pivoted so as to move the position shown in full lines to that shown by dotted lines, Fig. 2.

The mechanism is so arranged that, when both levers are in the position shown in Fig.- 2, the current is cut oif. VVhenthe lever 4 is moved to the position shown by dotted lines, the low heat circuit is closed. When the lever 5 is moved to the position shown by dotted lines and the lever 4. is in the position shown in full lines, the medium heat circuit is closed. When both levers are in the position illustrated in Fig. lof the drawings, both circuits are closed, which produces auhigh heat.

The wires'extend through center openings in the caps 6, which are screwed onto the casing in the present instance. The raised button 7 indicates the on position.

In order to distinguish the levers, the finger pad of the lever 4 is arranged at right angles to the pad of the lever 5. The lever 5 is flat, while the lever 4 is twisted, as shown. 5 By the construction hereinbefore described, the switch can be turned accurately in the, dark so that a heating pad, or other irticle, will receive the desired amount of eat.-

It will be understood that the body of the switch can be made in any manner desired, as the invention is designed for use on any switch, in which two levers are located comparatively close together, or on a single switch structure.

I claim: k The combination in an electric switch, of a casing having two parallel slots therein; and two levers arranged side by side. one lever projecting through one slot and the other lever projecting through the other slot, each lever being provided with a finger pad, the pad of one lever being at right angles to the pad of the other lever.
